Dude, this was a concern since Cell and it was an estimate made by someone that isn’t just a hick with brain damage. Neither Goku or Android 16 operate at that sense of scale in the first place, but I’m going to trust the computer over a man that can barely pass a competency pen and paper exam at a time he has that frame of reference. Also, when Goku was talking this shit, Gohan was already dead. You’ve pushed weak evidence for Goku in the past, but this shit is sad :maybe EDIT - Only scenario that they can't kill Kid Buu is that his power doesn't decrease from suffering damage and that his regeneration is supposedly more bullshit than his other forms (and this is only possibly inference from when he atomized himself detonating Earth, not concretely stated; they didn't explore the limit to it anywhere else and Super Buu still returned from being literal vapor). The Spirit Bomb is power to overkill Kid Buu, the propellant force is what Kid Buu was able to contend with and that...
